What is fertilization , and where does fertilization occur
Softa [21]
In humans fertilization occurs in the end of the fallopian tube away from the uterus (close to the ovary). The egg and the associated cumulus cells are ovulated (released) from an ovarian follicle and picked up by the fallopian tube. The tube pulls it inside where the sperm can find it.

Explain how the use of genetically engineered products can affect the economy and society.
ZanzabumX [31]

Answer:

due to gmos we can expand the shelf life of many of our foods and prevent them from the harm of pests. You night be rhinking why not use pesticides? well, we did but eventually the pests became immune to the low dose of pesticide. over time we gradually increased our uses of pesticides. more commonly round up. this pesticide specifically was known for being a carcinogen. (something that causes cancer.) Genetically modifying a crop can severely decrease the amount of pesticides used for our crops and could also potentially drop the prices. for example, in hawaii during the 1940s to 1990s the ringspot viruses hit the hawaiian papaya harvest hard. this reduced the amount of papaya produced by 50 percent by 1993 and 2006. the ringspot virus nearly wiped out the entire crop. within 11 months, the hawaiian papya was saved. due to gmos of course. this is because scientists took genes from immune papayas which very rarelt occured (at the time) and injected it into many other papya plants. as the plants grew, new papaya was produced which was immine to ringspit virus. PAPAYA WAS SAVED!!!!
